What distro or build system are you using? It would also be helpful
to test whether the -march=armv4t/--fix-v4bx workaround produces
working binaries for you, in that case you could report to the gcc
developers that the removal of armv4 can continue but that
the --fix-v4bx option in ld needs to stay around.
